Shape
The radius has a body and two extremities. The upper extremity of the radius consists of a somewhat cylindrical head articulating with the ulna and the humerus, a neck, and a double tuberosity. The body of the radius is self-explanatory, and the lower extremity of the radius is roughly quadrilateral in shape, with articular surfaces for the ulna, scaphoid and lunate bones. The distal end of the radius forms a palpable point called the styloid process. Along with the proximal and distal radioulnar articulations, an interosseous membrane originates medially along the length of the body of the radius to attach the radius to the ulna.

Famous quotes containing the word shape:
““Must a name mean something?” Alice asked doubtfully.
“Of course it must,” Humpty Dumpty said with a short laugh: “my name means the shape I am—and a good handsome shape it is, too. With a name like yours, you might be any shape, almost.””
—Lewis Carroll [Charles Lutwidge Dodgson] (1832–1898)
“Surely among a rich man’s flowering lawns,
Amid the rustle of his planted hills,
Life overflows without ambitious pains;
And rains down life until the basin spills,
And mounts more dizzy high the more it rains
As though to choose whatever shape it wills....”
—William Butler Yeats (1865–1939)
“We cannot and must not get rid of nor deny our characteristics. But we can give them shape and direction.”
—Johann Wolfgang Von Goethe (1749–1832)
